A small earthquake was felt in and around the Montreal region early this morning, baffling some residents but causing no known damage.# \9 f, ~) {: ~" ~9 H; l. W# x* K" h
Natural Resources Canada seismologist Allison Bent said it was a magnitude 4.5 quake and was centred east of the city.

There were no reports of damage, although the quake did create jitters that had some people scurrying briefly from their houses./ a! m9 p2 L9 F3 c1 M4 g
Laval, just north of Montreal, received 911 calls — more than 1,060 of them within 20 minutes of the tremor. Montreal had a higher than normal volume of calls as well.* d i3 T' i$ j5 r* {( k
"People were asking what exactly was happening. The 911 operators worked a good chunk of the night to reassure people and answer the stream of calls," Const. Simon Delorme of Montreal police said.$ T: x& m9 H( L0 j& ^; e
The temblor lasted about 10 seconds, causing buildings to rumble. But Bent said any serious damage was highly unlikely, and both the Montreal and Laval police forces said they had no reports of any.

"We both looked at each other and think: 'We lived four years in Vancouver and we experience an earthquake in Montreal,' " she said. u; q7 ~: C3 c0 C9 l0 Y

Minor Montreal-area quakes commonCBC meteorologist Johanna Wagstaffe, who is also a seismologist, said the Montreal region has approximately one earthquake every five days, but most are too weak to be felt.4 K4 r: P4 A7 e( ^1 r: h
Before Wednesday, the most recent tremor of significant magnitude in the area was a 3.0 last Thursday located about six kilometres north of Huntingdon, a small community southwest of Montreal near the U.S. border. Three other earthquakes since Sept. 15 have been felt in Quebec, according to Natural Resources Canada.
